Experimental evaluation and numerical simulation of performance of the bypass dual throat nozzle
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2020Bypass dual throat nozzle (BDTN) is a modern concept of fluidic thrust vector control. This method able to solve the problem of thrust loss without need the secondary mass flow from other part of engine. Internal nozzle performance and thrust vector angles have been measured in the BDTN experimentally and numerically. A new simple approach is proposed

Preliminary Analysis and Design Enhancements of a Dual-Throat FTV Nozzle Concept
39th AIAA Fluid Dynamics Conference, 2009Fluidic thrust vectoring (FTV) can potentially provide the same advantages in aircraft control as traditional thrust vectoring which uses vanes and gimbals, but with reduced weight and radar signature. This paper provides a brief description of the various FTV techniques and a closer look at a novel dual-throat design.

Open and Closed-Loop Responses of a Dual-Throat Nozzle during Fluidic Thrust Vectoring
52nd AIAA/SAE/ASEE Joint Propulsion Conference, 2016The dynamic response of a Dual-Throat Nozzle in open and closed-loop control is investigate numerically. Thrust vectoring in fixed, symmetric nozzles is obtained by secondary flow injections that cause local flow separations, asymmetric pressure distributions and the vectoring of primary jet flow. The computational technique is based on a model for the

Performance study of bypass dual throat nozzle based on numerical simulation
International Journal of Turbo & Jet-EnginesAbstract This study investigates the aerodynamic performance of elliptical cross-section bypass double-throat nozzles (BDTNs) with varying short-to-long axis ratios (b/a = 1.0, 0.8, 0.6, 0.4), using an axisymmetric BDTN as a reference.

Bypass dual throat nozzles (BDTN) was first proposed in the 1990s as means to enable more effective and efficient control of combat aircraft, but real-world implementation has not yet been demonstrated. In an attempt to mitigate this gap, this study provides an extensive experimental investigation through conducting simultaneous pressure measurements ...
